CHILD SAFETY SEAT
TECHNICAL FIELD
[0001] Exemplary embodiments of the present disclosure generally relate to
child safety seats,
and more particularly, to a child safety seat that is lightweight while
employing an energy
absorbing support frame.
BACKGROUND
[0002] Child safety seats (or simply child safety seats or car seats) are
secured inside a vehicle
to protect children in vehicles from the effects of either accidents, sudden
deceleration, or other
impacts or jarring events. The child safety seat may include various different
protective features
relating to securing the child safety seats in the vehicle, securing the child
to the child safety seat,
and protecting the child once the child is secured in the child safety seat.
Some of these protective
features may be prescribed by regulation in certain jurisdictions, but others
may provide optional,
additional protection for children. Due to the variety of features included on
the child safety seat,
and even different structural arrangements for providing many of those
features, the child safety
seat may be heavy to carry and uncomfortable for a child occupying the child
safety seat.
BRIEF SUMMARY OF SOME EXAMPLES
[0003] Example embodiments described herein may therefore provide for a
lightweight and
comfortable child safety seat while still providing enhanced safety and
comfort features such as
energy absorption capabilities, side impact protection, and extended use from
infancy through
toddlerhood. In this respect, the child safety seat may have flexible mesh or
fabric sides that offer
greater comfort and air flow to the child seated therein while decreasing the
typical weight of the
child safety seat. Furthermore, the child safety seat may be configured for
both base and baseless
installation and have a support frame and cage frame that provide for enhanced
energy absorption
and side impact protection.
[0004] In one example embodiment, a child safety seat is provided. The child
safety seat
includes a seat shell configured to receive and secure a child therein. The
seat shell includes a top
portion, a base portion, and side portions operably coupling the top portion
to the base portion, and
the side portions are fabric or mesh. The child safety seat further includes a
support frame

743051/00070
configured to absorb energy and that defines a seat portion and backrest
portion of the child safety
seat to enable the child to be secured therein.
[0005] In another example embodiment, a child safety seat is provided. The
child safety seat
includes a base assembly configured to be operably coupled to a vehicle seat.
The child safety seat
further includes a seat shell configured to receive and secure a child
therein. The seat shell is
operably coupled to the base assembly such that the seat shell is alternately
movable between, and
engageable in, a plurality of positions relative to the base assembly. The
seat shell includes a top
portion, a base portion, and side portions operably coupling the top portion
to the base portion, and
the side portions are fabric or mesh. The child safety seat further includes a
support frame
configured to absorb energy and that defines a seat portion and backrest
portion of the child safety
seat to enable the child to be secured therein.
[0006] In an even further example embodiment, a base assembly of a child
safety seat is
provided. The base assembly operably couples a child safety seat to a vehicle
seat. The base
assembly includes a latch assembly configured to receive and secure a seat
shell of the child safety
seat in a plurality of rear-facing positions with respect to the base
assembly. The latch assembly
includes a plurality of latches that are configured to selectively receive
rods of the seat shell. The

DETAILED DESCRIPTION
[0023] Some example embodiments now will be described more fully hereinafter
with reference
to the accompanying drawings, in which some, but not all example embodiments
are shown.
Indeed, the examples described and pictured herein should not be construed as
being limiting as
to the scope, applicability, or configuration of the present disclosure.
Rather, these example
embodiments are provided so that this disclosure will satisfy applicable legal
requirements. Like
reference numerals refer to like elements throughout. Furthermore, as used
herein, the term "or"
is to be interpreted as a logical operator that results in true whenever one
or more of its operands
3
3783181
CA 3075121 2020-03-11
743051/00070
are true. As used herein, the phrase "operable coupling" and variants thereof
should be understood
to relate to direct or indirect connection that, in either case, enables
functional interconnection of
components that are operably coupled to each other.
[0024] As discussed above, some example embodiments may provide a lightweight,
safe, and
comfortable child safety seat that allows for extended use of the child safety
seat from infancy
through toddlerhood. In accordance with example embodiments, the child safety
seat may have
flexible mesh or fabric sides that offer decreased weight, greater comfort,
and air flow to the child
occupant while still providing enhanced safety protection features such as an
energy-absorbing
support frame and a side protection cage frame.
[0025] FIGS. 1 and 2 illustrate a child safety seat 10 according to example
embodiments
described herein. As shown in FIGS. 1 and 2, the child safety seat 10 may
include a seat shell 20.
The seat shell 20 may include components that enable an occupant (i.e., child)
to be seated,
secured, and supported in the child safety seat 10. In this regard as shown in
FIG. 2, the seat shell
20 may include a base portion 22, a top portion 24, and side portions 26
extending between or
operably coupling the base portion 22 and the top portion 24.
[0026] The base portion 22 may be a portion of the child safety seat 10 on
which the child safety
seat 10 is configured to be seated or rested on or, in some example
embodiments, is configured to
engage a base assembly 200 (see FIG. 9) for securing the child safety seat 10
in a vehicle. The
base portion 22 may be formed of a plastic or similar material.
[0027] The top portion 24 may be a portion of the child safety seat 10 to
which a handle portion
40 is configured to be operably coupled to and may form an opening 28 that is
configured to
receive the occupant. In this regard, the top portion 24 may be disposed on an
opposite side of the
child safety seat 10 from the base portion 22 (e.g., the top portion 24
forming an upper portion and
the base portion 22 forming a bottom portion of the child safety seat 10
relative to when the child
safety seat 10 is in a normal sitting position as shown in FIG. 2). The top
portion 24 may form a
rim around the opening 28 of the seat shell 20 to which components such as the
handle portion 40
and a cage frame 80 (as further discussed below) may be coupled to. In some
cases, the top portion
24 may be formed of a plastic or similar material.
[0028] Furthermore, the top portion 24 may include a first section 34 and a
second section 36
that each extend around an upper portion of the child safety seat to define
the opening 28. In order
to ensure that the child safety seat 10 is lightweight, the first section 34
may include a plurality of
4
3783181
CA 3075121 2020-03-11
743051/00070
ribs 37 formed of a plastic or similar material. The plurality of ribs 37 may
extend around the
opening 28, and each rib 37 may be spaced apart from other adjacent ribs 37 by
a hollow, open
space 38. These spaces 38 allow air to flow therethrough, which reduces or
eliminates any
unnecessary material from the child safety seat 10 thereby reducing the weight
of the child safety
seat 10. The second section 36 may be a solid, uniform piece formed of a
plastic or similar material
to allow for the handle portion 40 or the cage frame 80 to be attached thereto
(as further discussed
below).
[0029] As shown in FIG. 2, the handle portion 40 may be curved around the
opening 28 of the
child safety seat 10 defined by the top portion 24 to allow for an easy,
balanced carrying of the
child safety seat 10. The handle portion may include a first strap 46, a
second strap 48, and a
gripping member 50. In this respect, the first strap 46 and the second strap
48 are joined together
proximate a center of each of the straps 46, 48 at the gripping member 50 to
form the handle
portion 40. It should be understood, however, that in some example embodiments
that each strap
46, 48 may be formed of two separate strap portions that are coupled to the
gripping member 50
in order to form the handle portion 40. Regardless of the structure of the
handle portion 40, the
child safety seat 10 can be carried at the gripping member 50 which enables an
easy, balanced
carrying of the child safety seat 10.
[0030] In
some cases, the first strap 46 may have a longer length than the second strap
48 and
be operably coupled to the top portion 24 proximate a midsection of the child
safety seat 10. The
second strap 48 may have a shorter length than the first strap 46 and be
operably coupled to the
top portion 24 proximate a head portion 39 of the child safety seat 10 (e.g.,
the position proximate
where the child's head would be located when seated in the child safety seat
10). In this regard,
the second strap 48 may be located closer to a head portion 39 of the child
safety seat 10 than the
first strap 46. The length and placement of the straps 46, 48 of the handle
portion 40 allow for the
straps 46, 48 to nest or overlap each other when moved to a stowed position,
as further discussed
below. Furthermore, each of the straps 46, 48 may have a first end that is
configured to be operably
coupled to a first side 25 of the top portion 24 and a second end that is
configured to be operably
coupled to a second side 27 of the top portion 24. In this regard, each of the
straps may be curved
around the opening 28 of the child safety seat 10 defined by the top portion
24 to further enable
easy, balanced carrying of the child safety seat 10.
3783181
CA 3075121 2020-03-11

[0031]
Each of the straps 46, 48 of the handle portion 40 may be pivotably attached
between
the first and second sides 25, 27 of the top portion 24 such that the handle
portion 40 can be easily
adjusted between a carrying position (shown in FIG. 2) and a stowed position.
When the handle
portion 40 is in the carrying position, the handle portion 40 may be suspended
above the child
safety seat 10 to facilitate carrying of the child safety seat 10. When the
handle portion 40 is moved
to the stowed position (see arrow in FIG. 2 indicating movement of the handle
portion 40 from the
carrying position to the stowed position), the handle portion 40 may be
configured move down
and rest close to or adjacent to the top portion 24 to facilitate easy
insertion in and removal of the
occupant from the child safety seat 10. In this respect, when the handle
portion 40 is moving to the
stowed position, the first strap 46 pivots in a direction toward the second
strap 48 to overlap or
nest with the second strap 48 and be pivoted away from the opening 28 to allow
for insertion of
the child into the child safety seat 10.
[0032] As further shown in FIG. 2, the seat shell 20 may include the side
portions 26 that extend
from the top portion 24 to the base portion 22. In other words, the side
portions 26 form the sides
of the child safety seat 10 with the top portion 24 forming the upper portion
and the base portion
22 forming a bottom portion with respect to the child safety seat 10 being in
a normal sitting
position as shown in FIG 2. Each of the side portions 26 may be formed from a
fabric or mesh
panel allowing for the child safety seat 10 to not only be lightweight but
more breathable and
comfortable for the occupant. Furthermore, in some cases, the fabric or mesh
panel may be a
flexible panel to enable the child safety seat 10 to conform to the occupant
of the child safety seat
10. In this respect, the side portions 26 of the seat shell 20 are fabric and
the only portions of the
seat shell 20 made of a solid material (e.g., plastic or the like) are the top
portion 24 and the base
portion 24. A typical child safety seat is typically made of foam and plastic
in each of the analogous
top portion, bottom portion, and side portions leading to a child safety seat
that is heavier and
harder to carry. However, as example embodiments described herein provide for
side portions 26
formed of fabric or mesh, the child safety seat 10 is not only lightweight
(e.g., less than five pounds
in some cases) but is also configured to conform to the occupant seated in the
child safety seat 10
which makes for a more comfortable experience for the child.
[0033] As further shown in FIGS. 1-5, the child safety seat 10 may also
include a support frame
60. The support frame 60 is multi-functional in that the support frame 60 may
form the surface on
which the occupant is supported in the child safety seat 10 while also being
configured to absorb
6
3783181
CA 3075121 2020-03-11
743051/00070
energy in the event of an impact. As shown in FIGS. 2-5, the support frame 60
may be operably
coupled between each of the base portion 22 and the top portion 24. In this
respect, a first end 62
of the support frame 60 may be operably coupled to a first end 30 of the top
portion 24 of the child
safety seat 10 and may curve around such that a second end 64 of the support
frame 60 may be
operably coupled to a second end 32 of the top portion 24. Furthermore, at
least a portion of a
bottom surface 66 of the support frame 60 may be in contact with or operably
coupled to an interior
surface of the base portion 22 (the interior surface of the base portion 22
being opposite from an
exterior surface of the base portion 22 that is in contact with a surface when
the child safety seat
is in a normal, sitting position). In this regard, the placement and operably
coupling of the
support frame 60 between the top portion 24 and the base portion 22 may
maintain the position of
the support frame 60 within the seat shell 20 during normal use and during an
impact while the
support frame 60 defines the surface for supporting the occupant.
[0034] FIG. 6 illustrates a front view of the child safety seat 10 in
accordance with an example
embodiment herein. As shown in FIG. 6, the top surface 68 of the support frame
60 may define a
concave curvature that is configured to cradle and support the occupant seated
therein (see also
FIG. 3). In this respect, the side portions 26 may extend over or cover the
top surface 68 of the
support frame 60 to form the surface on which the occupant is configured to be
seated upon in the
child safety seat 10. The top surface 68 of the support frame 60 may define
the seat portion 70 and
the backrest portion 72 of the child safety seat 10. The seat portion 70 and
the backrest portion 72
may extend substantially perpendicularly away from an apex 74 at which they
meet. In this respect,
the apex 74 may be proximate a center of the base portion 22 of child safety
seat 10, and the seat
portion 70 may extend substantially horizontally from the apex 70. The
backrest portion 72 may
extend substantially vertically away from the apex 74.
[0035] While forming the seat portion 70 and the backrest portion 72, the
support frame 60 may
be also configured to reduce forces experienced by the occupant of the child
safety seat 10 as a
result of an impact. In other words, the support frame 60 may provide support
and form portions
of the child safety seat 10 during a normal use of the child safety seat 10.
However, when the
amount of force to the child safety seat 10 exceeds a predetermined amount
(e.g., as a result of an
impact in a crash), the support frame 60 may be configured to deform in order
to absorb the force
of the impact and thereby reduce the force experienced by the occupant of the
child safety seat 10.
In other words, the support frame 60 may be configured to support the seat
shell 20 and its occupant
7
3783181
CA 3075121 2020-03-11
743051/00070
and provide energy absorption in the event of an impact. As such, the support
frame 60 is multi-
functional in that the support frame 60 acts as at least a portion of the
frame of the child safety seat
while functioning as an energy absorber.
[0036] Furthermore, the support frame 60 is a multi-directional energy
absorber. In this regard,
the support frame 60 and the seat shell 20 maintain their position relative to
the base assembly 200
and thus the support frame 60 may provide energy absorption irrespective of a
position the seat
shell 20 is placed in relative to the base assembly 200. Traditional energy
absorbers were fixed in
a static position between a seat shell and a base assembly thus they were only
able to provided
energy absorption capabilities in one direction. However, in this example
embodiment, the support
frame 60 is coupled to the seat shell 20 and move together to a plurality of
different positions
relative to a fixed base assembly 200. Thus, the support surface 60 is
configured to provide energy
absorption in each of the plurality of positions the seat shell 20 is moved to
with respect to the base
assembly 200.
[0037] It should be understood that normal use and normal wear and tear of the
child safety seat
10 is not enough force to deform the support frame 60. For example, during
normal use (i.e.,
installed in a vehicle and occupied by a child), the amount of force exerted
upon the support frame
60 is not sufficient to deform the support frame 60. Similarly, during
installation and removal of
the child safety seat 10 and during hard-braking events or very minor impacts,
the threshold
amount of force required to deform the support frame 60 may not be achieved.
In this respect, the
support frame 60 is configured to deform as a result of a crash, hard impact,
etc. (e.g., events that
cause force that exceeds a predetermined level).
[0038] As
shown in any of FIGS. 2-6, the support frame 60 may be a unitary, molded
plastic
frame that is operably coupled to the top portion 24 and the base portion 22
of the child safety seat
10. In some cases, the support frame 60 may be hollow. However, in accordance
with other
example embodiments, the support frame 60 may be partially or fully filled
with an energy
absorbing material such as a gas, a liquid, a gel, a foam, or combination
thereof. For example, the
support frame 60 may be filled with a plastic or cellular material.
Accordingly, the support frame
60 may be formed of a deformable plastic, foam, rubber, or metal and, in some
cases, be filled
with a plastic, cellular, gas, liquid, gel, or foam material. The material
selected to form both the
exterior and interior of the support frame 60 may be selected based on their
configuration to deform
at a predefined force.
8
3783181
CA 3075121 2020-03-11
743051/00070
100391 As shown in FIGS. 3 and 4, the support frame 60 may have a webbed
structure. In this
regard, the bottom surface 66 of the support frame 60 may include a plurality
of energy absorption
cells 76 formed or defined by web members 78. In other words, the energy
absorption cells 76 may
be disposed between the top surface 68 of the support frame 60 and the base
portion 22. The
plurality of energy absorption cells 76 are connected or intersect with one
another, and in the event
of an impact, one or more of the web members 78 may be configured to flex or
break before other
rigid structures of the seat shell 20 break or flex. While the webbed
structure is demonstrated in
FIGS. 3 and 4, other example embodiments of the support frame 60 may include
the bottom surface
66 of the support frame 60 having a honeycomb structure, a closed cell
structure, or the like which,
similarly to the webbed structure, are configured to flex or break in the
event of an impact before
other rigid structures of the seat shell 20.
100401 FIG. 7 illustrates a rear view of the child safety seat 10 according to
an example
embodiment. As shown in FIG. 7, the support frame 60 may have an axis 79
extending down a
center of the support frame 60. Some embodiments may include the support frame
60 having a
single unitary bottom surface 66. However, in other example embodiments,
rather than having a
single unitary bottom surface 66 forming the plurality of energy absorption
cells 76, the support
frame 60 may have a first set of energy absorption cells 76 disposed on a
first side of the axis 79
and a second set of energy absorption cells 76 disposed on a second side of
the axis 79.
Furthermore, there may be a hollow space disposed between the first set and
second set. In other
words, the bottom surface 66 of the support frame 60 that is disposed beneath
the seat portion 70
of the support frame 60 may define the first and second set of the energy
absorption cells 76. The
bottom surface 66 of the support frame 60 that is disposed beneath the
backrest portion 72 of the
support frame 60 may define a single unitary frame that includes a plurality
of horizontally
extending slots 75 that are configured to receive a harness of the child
safety seat 10.
100411 As further shown in FIGS 1-4, the child safety 10 may also include a
cage frame 80. The
cage frame 80 may be operably coupled to the top portion 24 of the seat shell
20 and be configured
to provide side impact protection for the child safety seat 10. Similarly to
the support frame 60,
the cage frame 80 may be formed of a material configured to absorb energy as a
result of an impact.
In this respect, the cage frame 80 may be a unitary, molded plastic or metal
frame that is configured
to wrap around an exterior of the child safety seat 10 proximate the backrest
portion 72 and absorb
energy and deform to reduce the force of the impact experienced by the
occupant. The cage frame
9
3783181
CA 3075121 2020-03-11
743051/00070
80 may be hollow. However, in accordance with other example embodiments, the
cage frame 80
may be partially or fully filled with an energy absorbing material such as a
gas, a liquid, a gel, a
foam, or combination thereof. For example, the cage frame 80 may be filled
with a plastic or
cellular material. Accordingly, the cage frame 80 may be formed of a
deformable plastic, foam,
rubber, or metal material and, in some cases, be filled with a plastic,
cellular, gas, liquid, gel, or
foam material. The material selected to form both the exterior and interior of
the cage frame 80
may be selected based on their configuration to deform at a predefined force.
For example, the
cage frame 80 may be formed of a hollow aluminum and provide more structure
and rigidity to
the seat shell 20 around a head and back portion of a child seated therein and
be configured to
deform in order to absorb force in the event of an impact.
100421 The cage frame 80 may be configured to extend between the first side 25
and the second
side 27 of the top portion 24 around an exterior portion of the seat shell 20
in order to provide side
protection for the child safety seat 10. In accordance with some example
embodiments, the cage
frame 80 may include a first portion 82 and a second portion 84. In
embodiments where the cage
frame 80 includes a first portion 82 and a second portion 84, the first
portion 82 of the cage frame
80 may extend around the exterior of the seat shell 22 proximate the apex 74
of the support frame
60 between the first side 25 and the second side 27 of the top portion 24.
Furthermore, the second
portion 82 may extend around the exterior of the seat shell 20 proximate the
head portion 39 of the
seat shell 22 between respective sides of the first portion 82. By having a
first portion 82 and
second portion 82 of the cage frame 80, the first portion 82 provides impact
protection for each
respective side and backrest portion 72 of the child safety seat 10 while the
second portion 84 also
provides impact protection for each respective side and a head portion 39 of
the child safety seat
10. Accordingly, the cage frame 80 effectively provides coverage for a
substantial portion of an
exterior of the child safety seat 10 in order to absorb force experienced as a
result of an impact
thereby reducing the effects of the impact on the occupant.
100431 In accordance with even further example embodiments, the cage frame 80
may be
pivotably attached to each of the first side 25 and second side 27 of the top
portion 24 to enable
the cage frame 80 to be pivoted between an engaged position (see FIG. 3) and a
disengaged
position (see FIG. 5). In the engaged position shown in FIG. 3, the cage frame
80 may be
configured to provide enhanced side impact protection as discussed above. In
the disengaged
position shown in FIG. 5, the cage frame 80 may be configured to pivot in the
direction of arrow
3783181
CA 3075121 2020-03-11
743051/00070
83 toward and underneath the base portion 22 relative to a normal, sitting
position of the child
safety seat 10 thereby forming a stand for the child safety seat 10 to rest
upon. In this regard, in
the disengaged position, the cage frame 80 is configured to elevate the child
safety seat 10 off the
ground and serve as a stand on which the child safety seat 10 may rest.
Furthermore, in the
disengaged position when the cage frame 80 forms the stand, the child safety
seat 10 may be
configured to swing or rotate relative to and between the sides of the cage
frame 80 thereby
enabling the child safety seat 10 to function as a manual swing as desired.
Accordingly, similar to
the support frame 60, the cage frame 80 is multifunctional in that the cage
frame 80 provides for
side impact protection in the engaged position, and in the disengaged position
the cage frame 80
forms the stand for elevating the child safety seat 10 off the ground.
100441 In further example embodiments, the cage frame 80 may include a belt
guide 88 on each
respective side of the cage frame 80. In this respect, the child safety seat
10 may be installed via a
base assembly 200 (see FIG. 9) or baseless installation. When it is desired to
install the child safety
seat 10 without a base assembly 200, the belt guide 88 may be configured to
receive a seat belt of
the vehicle to secure the child safety seat 10 in the vehicle. As shown in
FIG. 3, the belt guide 88
may be disposed on each side of the cage frame 80 proximate the position where
the cage frame
80 is operably coupled to the top portion 24. In other words, the belt guides
88 are disposed at an
end of the first portion 82 of the cage frame 80 proximate where the cage
frame 80 is operably
coupled to the top portion 24 or the opening 28 is formed. Because the belt
guide 88 is provided
on each respective side of the child safety seat 10, one of the belt guides 88
are accessible
irrespective of which side of the vehicle the child safety seat 10 is disposed
on or desired to be
installed in.
[0045] The belt guide 88 defines or creates a path 89 (see FIG. 6) for
receiving the seat belt of
the vehicle. Each of the belt guides 88 define a slot for receiving the seat
belt to facilitate placement
of the seat belt to install the child safety seat 10 properly in the vehicle
in a rear-facing orientation.
As shown in FIG. 3, the slot may be substantially u-shaped for receiving the
seat belt. In this
regard, a lap portion of the seat belt may be routed through the slot of one
of the belt guides 88
and then guided along the path 89 and fed through the slot of the other of the
belt guides 88 to
install the child safety seat 10 in the vehicle. As shown in FIG. 6, the path
89 created by the slots
of the belt guides 88 may extend substantially parallel between the slots of
the belt guides 88 across
a width of the child safety seat 10.

[0046] In some cases, the belt guides 88 may include a lock-off device for
locking or securing
the vehicle or seat belt in the proper placement in order to prevent the seat
belt from loosening and
thereby ineffectively tensioning the child safety seat 10 to the vehicle seat.
In this regard, the lock-
off device may be configured to allow movement of the seat belt through the
slot in one direction
but restricts movement of the seat belt in the other direction. In other
words, the lock-off device
may be configured to allow the seat belt to be fed or routed through the slot
for securing the child
safety seat 10 to the vehicle seat while preventing the seat belt from moving
in an opposite
direction. In some case, the lock-off device may include or be a clamping or
pinching member that
permits the seat belt to be routed through the slot and clamps or pinches the
vehicle belt to secure
the seat belt and prevent movement of the seat belt in a direction opposite
from the direction the
belt is routed through the slot of the belt guide 88.

just support the bar 102, 104, or 106 received within. Furthermore, each of
the latches 230 and 240
may be disposed on a pedestal elevated further from the surface of the base
assembly than latch
220. In this regard, latch 210 may be located closest to the front end 260 and
the surface of the
base assembly 200 than latches 220, 230, 240 with each of the latches 220,
230, 240 being disposed
higher in elevation and closer to the rear end 270 than the latch located in
front of it (relative to
the front end 260). In this regard, the further the latch is disposed from the
front end 260 of the
base assembly 200 the higher in elevation the latch is.
100521 FIGS. 13-15 illustrate various positions of the seat shell 20 engaged
with the base
assembly 200. Based on the position (e.g., infant, baby, toddler, etc.) the
seat shell 20 is to be
installed in with respect to the base assembly 200, select latches 210, 220,
230, or 240 of the latch
assembly 202 may be configured to receive the rods 102, 104, or 106 of the
base installation
assembly 100. As shown in FIG. 13, the seat shell 20 is engaged with the base
assembly 200 to
position the seat shell 20 in a position to receive and comfortably and
properly seat an infant
weighing approximately 5-25 lbs. In FIG. 13, the base portion 22 of the child
safety seat 10 is
seated parallel or flush with a surface of the base assembly 200 to ensure
proper placement of the
infant in the child safety seat 10. To couple and lock the seat shell 20 in
the infant position, latch
210 is configured to receive and lock the rod 106 and latch 220 is configured
to receive rod and
lock the rod 104.

placed in the baby position
which slightly elevates the inclination of the seat shell 20 with respect to
the base assembly 200.
By increasing the inclination of the seat shell 20 with respect to the base
assembly 200, the child
seated in the seat shell may have more leg room and may be seated in a more
upwards position. In
this regard, a front end 300 of the child safety seat 10 may be maintained
proximate the base
assembly 200 while a back end 310 of the child safety seat 10 is elevated from
the base assembly
200 to thereby creating more leg room for the child and to sit the child in a
more upright sitting
